BURNER-HEAD AND SHADE-HOLDER FOR LAMPS.

Specification of Letters Patent. Patentgd June 19, 1917,

Application filed August 30, 1916. Serial No. 117,656.

New York, in the county and State of New York, have invented certain new and useful Improvements in Burner-Heads and Shade- Holders for Lamps, of which the following is a specification.

This invention relates to lamps, and particularly to the kind vaporizing a hydrocarbon fluid, as kerosene, gasolene, alcohol, and the like; and the object of the invention is to provide a burner head having a part thereof forming an air mixer of special construction; a further object of the invention is to so construct the burner head that a shade holder of special construction can be applied thereto.

' The invention is illustrated in the accompanying drawing, in which Figure 1, is a vertical section of a burner head and shade holder constructed in accordance with my invention;

Fig. 2, is an elevation of the. sameat right angles to Fig. 1; and

Fig. 3, is a bottom plan view of one of the parts.

In the drawing, like numerals of reference refer to the same part in each view.

In practice I provide a burner head having an air mixer 4, comprising an air intake 5, a port 6, for the entrance of the nozzle of the vaporizer (not shown), a flaring passageway 7 through the Bunsen tube 8, to the enlarged mixing chamber 9, from which are pendant, as shown, two tubes 10, and 11, with which may be connected two burners, as will be understood.

The novel feature of construction in the parts just described is the flaring passageway 7, leading from the air intake 5, to the mixing chamber 9. By making this passageway flaring, with the small end at the air intake and the large end communicating with the mixing chamber, the gas and air will expand as they commingle in passing through the same to'the air mixer 9. This prevents back pressure at the nozzle; and insures a perfect mixture of gas and air even with considerable variation of size of the orifice in the nozzle. This is quite an important feature for the reason that the orifice in the nozzle of the vaporizer is made quite smallonly a few thousandths of an inch. In use carbon may lodge and partly close up this orifice, or it may be enlarged in needling, as it does not take much friction to enlarge this orifice a ten thousandth of an inch, or so. By having the flaring passageway through the Bunsen tube a greater variation in the size of the orifice in the nozzle is permissible than where the passageway through the said tube is straight or has parallel sides.

For convenience in manufacture the part having the air intake passageway 5, is cast separately from the other part of the head; and this piece 12, is provided with a screw threaded. socket 13, whereby it may be .screwed on a nipple 14, on the other part.

The part 12, is also preferably provided with a hub 15, in which may be formed a socket 16, by means of which the entire head may be mounted on a supporting post, as will be understood. The part 12, may also contain the guide channel 17 for directing the vaporizer to the port 6, as will be understood.

By forming the part 12, as shown, I can provide the same with two integral posts, or standards 18, and 19, which project upwardly substantially parallel to each other, as shown clearly in Fig. 2; and these two posts form the guides, as well as the support for the shade holder 20, which is provided with sockets 21, adapted to fit over, and slide along these standards, while set screws 22, may be used to hold the shade holder 20, at different heights, as indicated by dotted lines in Fig. 2.

The main purpose of my invention is to provide a burner head with means to hold a shade holder in a firm, detachable manner. shade holder can easily be reversed as the sockets 21, thereof are made to slide along the'posts, or standards on the part 12. This being the case I may form on one side thereof a plurality of projections 23, sufficient in number to firmly hold a shade on the holder 20; and on the other side of the holder I may form a similar number of projections 24, on a different radius than the projections 23. where a shade of a different size can be held than the projections 23 will hold firmly, as will be clear. Thus, by placing,one side of the shade holder upward I can hold a shade of one size; and by placing the other side of the shade holder upward I can hold a shade of a different size. In either case I-Iowever,-as held, it is clearly seen the the shade can be held at different points of elevation by reason of the set screws 22.

All the parts are simple in construction, cheap to manufacture, and efficient in use.

I claim:

1. In a lamp, a burner head and shade holder, said burner head having a standard on each side thereof, and said shade holder being mounted on said standards, said shade holder having a plurality of projections on each side thereof, and means to hold said shade holder at different elevations on said standards.

2. In a lamp, a burner head and shade holder, said head having standards on the opposite sides thereof, and said shade holder having sockets adapted to slide along said standards, said shade holder also having projections on the opposite sides thereof whereby a lamp shade can be mounted on either side of the shade holder, the projections on one side being on a different radius than the projections on the other side.

3. In a lamp, a burner head provided with a plurality of standards, a shade holder adjustably mounted on said standards, said shade holder having means on each side thereof to hold a lamp shade, the meanson one side being adapted to hold a larger shade than the means on the other side, and means to hold either side of said shade holder on the shade-engaging side.

4. In a lamp, a burner head provided With a plurality of standards, and a shade holder adjustably mounted on said standards, said shade holder having projections on the opposite sides thereof, the projections on one side being on a different radius from the projections on the other side, for the purpose set forth. a
